Q: Can this antenna be mounted on a non-metal surface?
A: While it will physically sit there, the magnetic base acts as a ground plane. For best signal performance, we recommend mounting it on a metal surface.
Q: Is the 3-meter cable replaceable?
A: The cable is integrated into the base to ensure waterproof integrity. If you need a different length, please contact our support for customization.
